While trying to open SQL Window with a Postgis Database, I get the error below.

I can see that there are some problems with utf-8. My database has some Latin1 encoded tables. Using another "empty" database I don't get this error.

This is new both in 2.0.1 (dev) and 2.1.0. The same database worked well in both 1.8 and 1.9. I'm using Windows 7 64 in this machine. I will try in a linux machine latter

An error has occured while executing Python code:
